Still, in order to give every man due credit for any assistance given to bee culture, I will here, with pleasure, state a fact in this connection that had escaped my recollection at time of writing the previous article, namely, that the first _mention_ of the machine of Von Hruschka in the English language was made in the American Bee Gazette,[4] page 85, September No., 1866, edited by Rev. E. Van Slyke, in an article translated from the German, by the editor. And to this article, Mr. Langstroth was most probably indebted for his first idea of the honey extractor, as Mr. Van Slyke writes me as follows--“Mr. Langstroth himself, who visited me at my office the very next month after the publication, spoke in terms of the highest enthusiasm of the article, and said that from my description as published he was about to construct a machine for honey extraction.” &c. R. BICKFORD. _Seneca Falls, N. Y._, Oct. 5, 1870. [For the American Bee Journal.] Why are Two Queens Sometimes Found in One Hive? MR. EDITOR:--Mr. A. Green, in the October number of the Journal, gives an account of finding two queens in one hive. Other correspondents have also given us their knowledge of similar facts; but none have, I think, given us any reasons for such exceptions. Last fall I bought an Italian queen from a reliable breeder. She came recommended as A No. 1. I received her on the 8th of September. All the workers sent with her were dead, except two; and she was herself so benumbed by cold that I had quite a time of it bringing her back to vitality. Finally I succeeded in getting her quite lively, and introduced her to a tolerably weak swarm. On the 10th of October finely marked Italians were flying in front of the hive. I spared no pains in wintering. (I winter out-of-doors.) In April she had filled three cards of brood. I then gave her a card of drone-comb. She would not look at it, and I moved it back and put in its place a card of worker-comb, which she filled with eggs almost instanter. I then put the drone-comb in the middle of the cluster, and got about fifty drones. Of course I was stimulating, and kept plenty of honey in the hive. I put in other worker-comb, but she refused to lay any more. I then took out a frame to start a nucleus, and in about a week after, when examining the old stock, I found queen cells started and the old queen on the comb, apparently all right. In due course a young queen was hatched, and after destroying the queen-cells, she remained with the old queen ten days before she was fertilized, and at least a week after she was laying. At the end of three weeks the old queen was gone.
